GMO SGM Major Markets Fund | ||||||||||||||||||||||||||||||||||||||||||||
GMO SGM Major Markets Fund (formerly known as GMO Systematic Global Macro Opportunity Fund) | ||||||||||||||||||||||||||||||||||||||||||||
Investment objective | ||||||||||||||||||||||||||||||||||||||||||||
Long-term total return. | ||||||||||||||||||||||||||||||||||||||||||||
Fees and expenses | ||||||||||||||||||||||||||||||||||||||||||||
The table below describes the fees and expenses that you may bear if you buy and hold shares of the Fund. | ||||||||||||||||||||||||||||||||||||||||||||
Annual Fund operating expenses (expenses that you bear each year as a percentage of the value of your investment) | ||||||||||||||||||||||||||||||||||||||||||||
| ||||||||||||||||||||||||||||||||||||||||||||
Example | ||||||||||||||||||||||||||||||||||||||||||||
This example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The example assumes that you invest $10,000 in the Fund for the time periods indicated, regardless of whether or not you redeem your shares at the end of such periods. The example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same as those shown in the table. The amounts shown reflect the expense reimbursement and waiver noted in the expense table for the first year. Although your actual costs may be higher or lower, based on these assumptions your costs would be: | ||||||||||||||||||||||||||||||||||||||||||||
| ||||||||||||||||||||||||||||||||||||||||||||
| ||||||||||||||||||||||||||||||||||||||||||||
Portfolio turnover | ||||||||||||||||||||||||||||||||||||||||||||
The Fund pays transaction costs, such as commissions, when it buys and sells securities. A higher portfolio turnover rate may result in higher transaction costs and, when Fund shares are held in a taxable account, higher taxes. These costs, which are not reflected in Annual Fund operating expenses or in the Example, affect the Fund’s performance. During its fiscal year ended February 28, 2015, the Fund’s portfolio turnover rate (including the accounts of the Fund’s wholly-owned subsidiary, GMO Alternative Asset SPC Ltd., and excluding short-term investments) was 45% of the average value of its portfolio. | ||||||||||||||||||||||||||||||||||||||||||||
Principal investment strategies | ||||||||||||||||||||||||||||||||||||||||||||
The Fund typically invests in a range of global equity, bond, currency, and commodity markets using exchange-traded futures and forward non-U.S. exchange contracts, as well as making other investments. The Fund seeks to take advantage of GMO’s proprietary investment models for global tactical asset allocation and equity, bond, currency, and commodity market selection. The Fund normally invests assets not held as margin for futures or forward transactions or paid as option premiums in cash directly (i.e., Treasury Bills) or money market funds. The Fund also may invest in U.S. and non-U.S. fixed income securities of any credit quality, maturity or duration and in shares of other GMO Funds (such other GMO Funds, the “underlying GMO Funds”), including GMO U.S. Treasury Fund (“U.S. Treasury Fund”), which is described in a separate prospectus. See “Investment in Other GMO Funds” below for a more detailed description of U.S. Treasury Fund’s investment objective and strategies. GMO’s models for this systematic process are based on the following strategies:
GMO may eliminate strategies or add new strategies in response to additional research, changing market conditions, or other factors. The factors considered and investment methods used by GMO can change over time. The Fund may gain exposure to commodities and some other assets by investing through a wholly-owned subsidiary. GMO serves as the investment manager to this subsidiary but does not receive any additional management or other fees for its services. The subsidiary invests primarily in commodity-related derivatives and fixed income securities, but also may invest in any other investments in which the Fund may invest directly. References in this Prospectus to the Fund may refer to actions undertaken by the Fund or the subsidiary company. The Fund does not invest directly in commodities and commodity-related derivatives. The Fund’s benchmark is the Citigroup 3-Month Treasury Bill Index. The Fund does not maintain a specified interest rate duration for its portfolio. The Fund is not limited in its use of derivatives or in the total notional value of its derivative positions. As a result of its derivative positions, the Fund typically has gross investment exposures in excess of its net assets (i.e., the Fund typically is leveraged) and therefore is subject to heightened risk of loss. The Fund’s performance can depend substantially, if not primarily, on the performance of assets or indices underlying its derivatives even though it does not own those assets or indices. | ||||||||||||||||||||||||||||||||||||||||||||
Principal risks of investing in the Fund | ||||||||||||||||||||||||||||||||||||||||||||
The value of the Fund’s shares changes with the value of the Fund’s investments. Many factors can affect this value, and you may lose money by investing in the Fund. An investment in the Fund is subject to different risks, and greater overall risk, than an investment in the underlying components of the Fund’s benchmark. References to investments include those held directly by the Fund and indirectly through the Fund’s investments in its wholly-owned subsidiary and in underlying funds. The Fund and some of the underlying GMO Funds are non-diversified investment companies under the Investment Company Act of 1940, as amended, and therefore a decline in the market price of a particular security held by the Fund or those underlying GMO Funds may affect the Fund’s or an underlying GMO Fund’s performance more than if the Fund or the underlying GMO Fund were a diversified investment company. The principal risks of investing in the Fund are summarized below. For a more complete discussion of these risks, including those risks to which the Fund is exposed as a result of its investments in its wholly-owned subsidiary and in underlying funds, see “Description of Principal Risks.”
| ||||||||||||||||||||||||||||||||||||||||||||
Performance | ||||||||||||||||||||||||||||||||||||||||||||
The bar chart and table below provide some indication of the risks of investing in the Fund by showing changes in the Fund’s annual total returns from year to year for the periods indicated and by comparing the Fund’s average annual total returns for different calendar periods with those of a broad-based index and a composite index computed by GMO. After-tax returns are calculated using the historical highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on your tax situation and may differ from those shown. After-tax returns shown are not relevant if you are tax-exempt or if you hold your Fund shares through tax-deferred arrangements (such as a 401(k) plan or individual retirement account). Updated performance information for the Fund is available at www.gmo.com. Past performance (before and after taxes) is not an indication of future performance. Prior to October 3, 2011, the Fund was managed pursuant to a materially different investment strategy and would have achieved materially different performance results from those shown for periods prior to October 3, 2011 under its current investment strategy. | ||||||||||||||||||||||||||||||||||||||||||||
